BBC Mufflers

Postby gtransue » Fri Mar 18, 2016 3:13 pm

Just looking for a few recommendations for my 496. I need the part numbers to look them up, and have them shipped up.

:thumbleft: :thumbleft: :thumbleft: I agree on the 3" dia. inlet and outlet too, but with a motor the size of yours you may want to go even a little longer than 12" if you can. Volume makes power .... shorty mufflers kill it.
Think of your engine as a big air compressor. Only four cylinders are going to fire on every revolution, but a 5,000 rpm that's a lot of hot exhaust gasses to be moved through two 3" tailpipes.

The 3 inch works on the big inch Cadillac. Ran this past week with a guy who used "Jones Turbine" stainless mufflers. More a straight thru than a turbo but they worked well and looked sweet.

Just be aware if ordering online and your not physically matching things up. There is OD and ID and some applications require one of each. My thru hulls require an ID but the flex pipe mates to an OD.
